Terraform Cloud's Business tier introduces enterprise-class features, including Single sign-on, self-hosted agents, audit logging capabilities, and a new API service called Audit Trails, which provides a JSON-based API to retrieve audit events for the entire organization. The Terraform Cloud for Splunk app integrates Terraform Cloud's audit logging with customers' existing Splunk Cloud or Splunk Enterprise implementations, providing near real-time visibility into key actions. With this integration, organizations can gain visibility across their entire Terraform organization and have a historical record of exactly what is happening, enabling them to identify trends, detect anomalies, and optimize their operations.
